Phys.org / SimCells successfully target and kill drug-resistant bacteria
We are continually in an evolutionary arms race with bacteria. As we develop new antibiotics, they develop resistance, and so it goes on until some of our treatments no longer work. Superbugs and antimicrobial resistance ...
Medical Xpress / Largest genome study of urban Peruvians unlocks clues for precision medicine
Latin American people are represented in fewer than 4% of genetic epidemiological studies around the world. When they are included, they're often lumped together as one group, despite the rich diversity among different Latin ...
Phys.org / Researchers present first fossilized 'emperor' butterfly
Butterfly fossils are rare, and finds that preserve fine anatomical details and wing patterns are an absolute exception. An international research team from Sweden, the U.S., and Germany, led by Dr. Hossein Rajaei, lepidopterist ...
Phys.org / A 500-million-year-old clawed predator rewrites the origin of spiders and horseshoe crabs
It had been a long day of teaching for Rudy Lerosey-Aubril. As a reward, he returned to cleaning an intriguing Cambrian arthropod fossil he had recently received for review. At first, the specimen showed all the expected ...
Medical Xpress / Cannabis and tobacco use linked to smaller brain volume
Cannabis and tobacco—whether used on their own or together—can affect the brain's structure. A recent study involving systematic review and meta-analysis of more than 103 studies found that both substances are linked to reduced ...
Phys.org / Gemini South confirms long-suspected link between the composition of exoplanets and their host stars
Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever ...
Phys.org / Gaia analysis finds Messier 35 is larger and older than earlier estimates
Astronomers from Egypt and Turkey have conducted a comprehensive analysis of kinematic, structural, and astrophysical parameters of a nearby open cluster known as NGC 2168. Results of the new study, published March 23 on ...
Phys.org / Time lapse video shows trees give visual clues as they rehydrate each spring
With the arrival of spring a few weeks ago, new buds and colors on the trees started to appear. Along with that new growth, a UBC Okanagan researcher has determined that some trees in spring also provide simple, visual clues—raised ...
Phys.org / Fins, fingers and toes: A new take on repeating body parts and how they come to be
As biologists know, nature can take its sweet time explaining itself. Andrew Gillis, associate scientist at the Marine Biological Laboratory (MBL), has been investigating how the paired fins of fishes evolved for nearly 20 ...
Phys.org / Nature's photocopiers caught 'doodling'—scientists say it could revolutionize how DNA is written
New research has discovered that the molecular machines responsible for copying our DNA have a surprising hidden talent—an ability to create entirely new and highly sophisticated DNA sequences from scratch. The study, led ...
Medical Xpress / New, more effective delivery method for eye cancer treatment is derived from pig semen
Getting past the barrier surrounding the eye is a difficult but necessary part of treating retinoblastoma (RB)—a form of eye cancer that is more common in children. Once the barrier is penetrated, RB responds well to treatment. ...
Tech Xplore / Lithium-air batteries break performance barriers thanks to a newly developed 2D catalyst
As the electric vehicle and energy storage system (ESS) markets experience rapid growth, the development of next-generation batteries capable of surpassing the energy density limitations of existing lithium-ion batteries ...
